If a symbol is repeated twice or thrice, the value of the numeral is obtained by adding the values of the symbol as many times as it is repeated. Examples:
II = 1+1 = 2
III = 1+1+1 =3
XX = 10+10 = 20 Note: The symbol V is never repeated.
To write a number in which the smallest digit always comes to the right of the greater digit, we add the values of all the digits. Examples:
VII = 5 + 1 + 1 = 7
XI = 10 + 5 = 15
LXVI = 50 + 10 + 5 +1 = 66
To write a number in which the smaller digit is placed before the greater digit, we subtract the value of the smaller digit from that of the greater digit. Examples:
IV = 5 - 1 = 4
LIX = 50 + (10-1) = 59 Note: The symbol V is never subtracted.
For the number beyond 10, we first write the number in groups of 10s and Is and then form the Roman numeral corresponding to the given number. Examples:
12 = 10+2 = XII
20 = 10+10 = X+X = XX
24 = 10+10+4 = 10+10+(5-1) = X+X+IV = XXIV
26 = 10+10+6 = XXVI
39 = 10+10+10+9 = XXXIX
Directions: Answer the following questions. Also write a table for roman numerals from 1 - 40 and ten examples of your own.
